Structural Equation Models SEMs which also can mentioned as simultanoes equation models is multivariate regression models. SEM have two
component model that is measurement model and structural model. SEM have two purpose the first is to determine what model sensible or fit or model the correctness pursuant to the data which have. Second is to test various hypothesis which have built before all. Standardization of estimation parameter of which branch far from expectation hence possible that is hypothesis wrong or the model which misspecified. One common which case is when the estimation from error variance is negative Heywood Case. Purpose of research is searching level of
influence from five construct variable benih obat pupuk opete intensif to storey productivity of paddy rice field by using SEM analysis. Result of from research this the total influence from latent variable intensif which consist of only one indicator is intensification have positive influence equal
to 016 and have a meaning of to latent variable produkti. The total influence from variable laten benih concidering indicator varietas indicator quality of seed and amount seed variable of obat which consist of the indicator variable irrigation and
usage of pesticide variable of pupuk which consist of the indicator variable usage of manure and amount of manure and variable opete dont have to mean although significant at result test. Level of totalize the influence to latent variable produkti
each of 001 006 033 and 056.
